Abstract

An apparatus for manufacturing a vehicular lamp that is formed by a lamp body and a translucent cover welded to the lamp body, the apparatus including a first heating element, which has a heating surface of substantially the same surface shape as the intended welding surface of the translucent cover and extends along the cover's intended welding surface, and a second heating element, which has a heating surface of substantially the same surface shape as the intended welding surface of the lamp body and extends along the lamp body's intended welding surface. The first and second heating elements are made of a resistance heating material.

Claims

exact text as granted — not AI-modified
1 . An apparatus for manufacturing a vehicular lamp comprised of a translucent cover and a lamp body that are welded together, the welding being carried out by heating intended welding surfaces of the translucent cover and lamp body and then pressing the intended welding surfaces against each other, wherein 
 said apparatus includes a heating element having a heating surface which has substantially the same surface shape as the intended welding surface of the translucent cover or the intended welding surface of the lamp body and extends along the intended welding surface; and    said heating element is made of a resistance heating material that generates heat upon application of electricity thereto.    
     
     
         2 . The apparatus according to  claim 1 , wherein said heating element has substantially the same cross section along an entire length of the heating surface of said heating element.  
     
     
         3 . The apparatus according to  claim 1 , wherein heating is carried out with the heating surface of said heating element positioned near the intended welding surface with a gap in between.  
     
     
         4 . The apparatus according to  claim 2 , wherein heating is carried out with the heating surface of said heating element positioned near the intended welding surface with a gap in between.  
     
     
         5 . The apparatus according to  claim 3 , wherein a ceramic coat layer is provided on the heating surface of said heating element.  
     
     
         6 . The apparatus according to  claim 4 , wherein a ceramic coat layer is provided on the heating surface of said heating element.
